GRAIN-SHOCK ELEVATGR.

Specification of Letters Patent.

Patented March 16, 1909.

Application filed August 21, 1907. Serial No. 389,487.

T o all whom it may concern:

Be it known that l, JOHN JAMEs, a citizen of the United States, residing at Oklahcma city, in the county of Oklahoma, Oklahoma, have invented certain new and useful lmprovements in Grain-Shock Elevators, of which the following is a specification.

My invention relates to grain shock elevators, in which a frame is mounted upon a pair of front traction wheels and a rear guiding wheel; a series of forwardly projecting fingers to glide under the shocks to raise them from the ground, a pair of rakes extending across the machine and having their ends pivotally secured to a pair of chain belts carried by four sprocket wheels to slide the grain shocks up a first or primary elevator, a transverse carrier being provided to carry and deliver the said shocks to a secondary elevator to elevate and discharge them onto a wagon or other conveyance, the said rakes having position and tilting devices secured thereto and to their belts, all of which will hereinafter be fully described and pointed out in the claims.

The objects of my invention are to provide a machine by which shocks of grain can be taken from the field, elevated and discharged at its side onto a wagon or other conveyance to transport the same to a thresher; to save time and labor in the process of threshing shocked grain. l accomplish these objects by the mechanism illustrated in the accompanying drawings, forming a part of this specification, in which- Figure 1 is a perspective of the machine embodying the elements of my invention; Fig. 2 is a plan view of the secondary or discharging elevator, Fig. 3 is a plan view of the lower frame, obscur-ing parts being removed; Fig. Ll is a plan view of part of one of the pairs of chain belts and one of the rakes showing the tilting device, Fig. 5 is an elevation of a portion of one of the chain belts with its rake-tilting device and one of the four like sprocket wheels; Fig. 6 is similar to Fig. 5, showing the rake in a discharging position.

Similar letters refer to similar parts in the several views.

Referring to the drawings, it will be seen that the side sills A and A are stayed by a cross sill B from which point the side sills rearwardly converge and unite in one doublesill projection O, having a drivers seat D secured thereon and being carried by a caster ward movement of their points material guide wheel E, at the converging bend in the side sills the upright posts F and F have their feet secured thereto; said posts have j ournaled at their upper ends the shaft K with the sprocket wheels J, l and G, the two latter carrying the chain belts H and L, ben ing rotated by the sprocket wheel J, the chain belt M and the sprocket wheel N by means of the clutch O (see Fig. 3) secured upon the main driving shaft F supporting the framework of the machine and being rotated by the two traction wheels Q and R.

To raise the shocks of grain from the ground a series of forwardly projecting fingers a, a, a having their forward end portions bent upwardly to glide under the shocks of grain and having their rear ends bent downs ward and forward and secured in the rear side of the fork head b having its ends pivotally secured in the sills A and A a short distance forward from their bearings; a short distance rearward from said fork head a cross bar c is placed having its ends bolted to the sills A and A to form a support for the lower ends of the elevator slats c', c constituting a support for the ascending grain shocks, the upper ends of said slats being secured to the cross bar d, having its ends bolted to the posts F and F.

To force the shocks of grain to ascend upward on the slats c', c', a Aplurality of hori- Zontal rake heads e, e are provided having a series of teeth e', c secured transversely therein and projecting in opposite directions therefrom, the said rake heads having their ends ivotally attached to the chain belts H andjL by means of the rake head journals f passing laterally through openings provided therefor inthe links q of said chain belts, the journals f being perforated for cotter pins f, see Figs. 1, 3 and 4L. To provide means to force the rake teeth c c to engage and discharge the grain shocks pro j erly each rake head c has near its ends fir y secured therein laterally projecting yokes 7L, having pivotally secured thereto one end of the rake controlling and tilting rods i their opposite ends being pivotally secured to the links g of the chain belts H and L by the bolts i passing through said links and the forward ends of said tilting rods, the bolts i being threaded and provided with nuts i to insure engagement, see Fig. 4; by this device positiveness of movement and position of the rake teeth are maintained and the upretarded at the time of discharging the grain shocks thus making a clean discharge, see Fig. 6, in which position the rake teeth are shown as having made the discharge, the direction of movement being indicated by the arrow.

Near the front ends of the side sills A and A are iournaled the 'duplicate sprocket Wheels l and G carrying the chain belts H and L operating the rakes e attached thereto, see Figs. l and 3.- To disengage the clutch O and thus throw the raking mechanism out of gear, any convenient device may be adopted, that shown in Fig. 3 being preferable, in which a rod j having a handle 7" Within reach of the operator is attached to the lever rod lc, its front end being U-shaped and engaging the said clutch, the said rod being pivoted to a supporting bar Z and having an auxiliary supporting bar Z both being secured to the side sill A and extending horizontally outward therefrom.

The elevator above described is properly a riinary elevator constructed for rearward de ivery; to establish a side delivery inachine a transverse platform-like carrier A is rovided, consisting of the side plates T an T having their lower edges resting upon the horizontal supporting arms U and U having their inner ends secured to the frame 'osts F and F and extending rearwardly andeing su ported by the rear post F, the foot of wliich is secured in the united portion of the said sills. The said side plates T and T have journaled in their ends the horizontal shafts m and m having mounted thereon four like belt pulleys to operate the belts n to'which the series of slats a are secured, for the purpose of moving the grain shocks in a direction transversely to the machine and delivering them to the secondary or discharging elevator B consisting of duplicate side plates V and V having their lower ends secured to the side lates T and T, at an angle therewith, and) having journaled in their upper and lower ends the horizontal elevator shafts 0 and o having mounted thereon the four belt sprocket pulleys p to operate the pair of chain belts p, p having secured thereto the elevator slats ln, provided with short barbs y to elevate and discharge the grain shocks. To operate the said belts (p) the shafts 0 and o have secured thereon the s rocket wheels z and s provided with the e ain belt g and driven by means of the sprocket wheels g and q mounted upon the shafts m and o and the short chain belt Q adapted to said wheels; the shaft m being rotated by the sprocket Wheel s secured thereon and, by its driving belt s engaging the sprocket wheel r secured upon the rear end of the horizontal driving shaft a having secured upon its forward end the bevel pinion t to operate the said carrier and` the secondary or discharging elevator VB, the said driving shaft is vjournaled ion twith the bevel wheel u the ratchet a is laced upon the shaft a in a manner to slice into and out of engagement with the ratchet portion'of the said bevel pinion, and to actuate the ratchet a and thus throw the carrier A and the secondary elevator B in and out of gear, the lever support a" is secured to the cross-bar B and has pivotally secured in its free end the actuating lever zu having attached thereto the operating rod x attached to the drivers controlling lever fu, see Fig. 3.

To the front ends of the side sills A and A are secured the lead rods X and X having eyes in their front ends in which to tie the lead-straps of the horses bridles; and to prevent the horses being injured by the traction wheels of the machine the guards or fenders Y and Y are provided, having their ends secured to the said side sills and having their body portions extending parallel with the machine and outside thereof, see Fig. 3.

In operation the fork fingers a, a, a, a glide under the grain shocks and raise the same from the ground bringing them within reach of the rakes c, e which seize the grain shocks and force them up the primary elevator and discharge them upon the transverse carrier A which carries them to the foot of the secondary or discharging elevator B, which dumps them onto a wagon or other conveyance prepared to receive and transport them to the threshing machine` Having thus described my invention what I claim as new and desire to secure by Letters Patent is zl.
